Technical and maintenance staﬀ must have theoretical and practical training in the ﬁeld of ventilation systems and should

be able to work in accordance with workplace safety rules as well as construction norms and standards applicable in the

territory of the country.

This unit is not intended for use by persons (including children)

with reduced physical, sensory or mental capabilities, or lack of

experience and knowledge, unless they have been given supervision

or instruction concerning use of the unit by a person responsible for

their safety.

Children should be supervised to ensure that they do not play with

the unit.

This appliance can be used by children aged from 8 years and above

and persons with reduced physical, sensory or mental capabilities or

lack of experience and knowledge if they have been given supervision

or instruction concerning use of the appliance in a safe way and

understand the hazards involved.

Cleaning and user maintenance shall not be made by children

without supervision.

Children shall not play with the appliance.

Connection to the mains must be made through a disconnecting

device, which is integrated into the ﬁxed wiring system in accordance

with the wiring rules for design of electrical units, and has a contact

separation in all poles that allows for full disconnection under

overvoltage category III conditions.

If the supply cord is damaged, it must be replaced by the

manufacturer, its service agent, or similarly qualiﬁed persons in order

to avoid a safety hazard.

Ensure that the unit is switched oﬀ from the supply mains before

removing the guard.

Precautions must be taken to avoid the back-ﬂow of gases into the

room from the open ﬂue of gas or other fuel-burning appliances.

The appliance may adversely aﬀect the safe operation of appliances

burning gas or other fuels (including those in other rooms) due to

back ﬂow of combustion gases. These gases can potentially result

in carbon monoxide poisoning. After installation of the unit the

operation of ﬂued gas appliances should be tested by a competent

person to ensure that back ﬂow of combustion gases does not occur.

All operations described in this manual must be performed by

qualiﬁed personnel only, properly trained and qualiﬁed to install,

make electrical connections and maintain ventilation units.

Do not attempt to install the product, connect it to the mains, or

perform maintenance yourself.

This is unsafe and impossible without special knowledge.

TECHNICAL DATA

To comply with the ErP 2018 regulation, a local demand controller and speed controller must be used.

MOUNTING

The fan is suitable both for horizontal or vertical mounting on the ﬂoor, on the wall or on the ceiling. The fan can be installed

independently or as part of a set with parallel or in-series connection.

min 1 m

The diameter of the spigots in the Stream 100/125 model can be changed using adapters, and in the Stream 150/160 model

using the rubber seal.

On outlet (discharge) spigot side it is necessary to install:

• in case of horizontal installation – a duct with a length of at least 1 m;

• in case of vertical installation – a canopy preventing moisture from getting into the fan.

The outlet spigot must always be connected to the air duct.

ELECTRONICS OPERATION ALGORITHM

Stream...P Stream...U, Un

Stream

The fan speed without options can be controlled by voltage, as well as by thyristor controllers.

A speed controller can be purchased separately.

Warning! When adjusting the voltage, ensure that there is no unusual noise or vibration at reduced motor speed.

When adjusting the voltage, the motor current may exceed the rated current.

The fan is equipped with a thermal switch without self-reset.

Probable causes of the thermal switch tripping:

• non-compliance with the operating rules

• impeller jamming (clean the impeller)

• motor malfunction (turn oﬀ the unit, contact the Seller)

To reset the thermostat:

• Switch oﬀ the power supply.

• Find and eliminate the cause of overheating.

• Switch the power back on.

The Stream ...T fan activates upon control voltage application to the LT input terminal by the external switch (e.g. indoor

light switch). After the control voltage is oﬀ, the fan continues to operate within the set time period adjustable from 2 to 30

min by the timer.

To adjust the fan turn-on delay time, turn the control knob T clockwise to increase and counter-clockwise to decrease the

turn-on delay time respectively.

WARNING! The timer circuit is live! Disconnect the fan from power supply prior to any adjustment operations.

The fan delivery set includes a specially designed plastic screwdriver for fan settings adjustments.

Use it to change the turn-oﬀ delay time and the humidity set point.

Do not use a metal screwdriver, knife, etc. for adjustment operations not to damage the circuit board.

The Stream ...U/Un fan is equipped with a TSC electronic module (speed controller with an electronic thermostat) for

automatic speed control (air ﬂow) depending on the air temperature.

The terminal compartment incorporates 2 control knobs:

• presetting speed;

• setting electric thermostat threshold value.

This indicator lights when the air temperature exceeds the set value.

To set the thermostat threshold, rotate the thermostat control knob clockwise to increase or counter-clockwise to decrease

the temperature set point accordingly.

To set the fan speed (air capacity), rotate the speed control knob in the same way.

The fan operating logic may be based on temperature or timer indications:

As the air temperature drops 2 °C below the set point or if the initial temperature is below the set point, the fan operates

with the set speed.

The Stream ...P fan is equipped with a speed controller that enables switching the fan on/oﬀ and smooth speed (air ﬂow)

regulation from minimum to maximum value.

Stream EC

The EC motor is controlled by sending of an external control signal from 0 to 10 V to the X2 terminal block or by the R1

internal speed controller. Control method selection is carried out by means of the SW DIP switch:

• DIP switch in IN position. The control signal is set by the R1 internal speed controller that enables switching the fan on/oﬀ

and smooth speed (air ﬂow) regulation from minimum to maximum value. Rotations are controlled from the minimum

(extreme right position) to the maximum (extreme left position). When rotating counter-clockwise, the rotations increase.

• DIP switch in EXT position. The control signal is set by the R2 external control unit.

DO NOT USE A METAL SCREWDRIVER, KNIFE, ETC. FOR ADJUSTMENT

OPERATIONS NOT TO DAMAGE THE CIRCUIT BOARD
